Patented Sept. 6, 1932 PATENT OFFICE Loose-L AF BINDER Application filed February 8, 1930.,Seria1 No. 426,871.

This invention relates to loose leaf binders and it has particular referencefto a binder.

provided with means for simultaneously releasing a plurality of leaf fasteners. '15

It has heretofore been proposedto form a loose leaf binder with a plurality of fastening devices which could be individually and separately secured to or released from members adapted to secure anumber of leaves.

contained in the binder; The present "invention provides means whereby'several fastening members may be operated at one time, and, more specifically, the invention contem- 15, plates the provision of means whereby the fastening deviceson both sides of a group of leaves may be concurrently operated and will release the leaf-securing. members at either of their ends without, at the same time, releasing their otherends.

As hereinafter more fully explained, the objects of theinventionmay be attained by providing a binder or cover with a. plurality of fasteners disposed within the cover, which may be interlocked with prongs passing through the leaves by a rod o'rbar extending longitudinally of the cover, and which, when moved in one direction, releases the fastening devices on onev side from the correspondingprongs, effects a similar release for. the prongs on the other slde when moved in the opposite direction, and, when maintained in an intermediate position, sec'uresthe fastening devices and prongs'on both sides of the stack of leaves. This embodiment of the invention, which permits of increased ease of assembly or removal of leaves from the stack, is illustrated in the accompanying drawings, wherein:

Fig. 1 is a view in perspective of an open binder containing a plurality of leaves locked therein;

Fig. 2 is a view in perspective of an open binder with the fastening means disengaged 7 from one side of the leaf. stack;

Fig; 3 is a view in perspective of the fastening means detached from'the binder;

Fig. 4 is a view in perspective of the leafimpaling means; Y

Fig. 5 is a'vertical transverse cross-sectional of leaves 13 securely, but in such manner that they may be freely removed, replaced, or rearranged. A series of marginal perforations in the leaves 13 is adapted to receive leafimpaling' means, shown in detail in Fig. 4, comprising a pair of opposed transfer bars 14 and 15, each having associated therewith a series of leaf posts 16. v The leaf posts 16 are fixedly disposed in apertures provided in the bars-1 1 and 15 and have reduced portions 18 protruding from the opposite side of the'bars. The free ends of the leaf posts 16 are provided with reduced portions 19 adapted to be received by registering apertures 20 provided in the complementary transfer bar.

The transfer bars 14 and 15 are arranged on opposite sides of the pile. of leavesv 13 with the leaf posts 16 disposed in the perforations thereof and with the reduced portion 19 of each leaf post extending through the aperture 20 in the opposed transfer bar. The reduced portions 18 and 19 are thus aligned on the outside of each transfer bar 14.0r 15, (Fig. 2) and areeach provided with an annular groove 22-adapted to be engaged by a fastening device which .Will presently be de y scribed. p

A piece ofcloth' 23 is glued or otherwise secured across the entire innerface of the back 12, and is provided with transversely T01\TAWANDA,.NEW YORK, ASSIGNOR TO REMINGTON RAND I me, or BnrrAL nnw YORK a of the cloth 23 are removed in the region of each pair'of apertures 26 to accommodatea fastener or. looking plate 27', slidablyi nount:

and 29 formed thereon at its opposite edges.

1 ed upon. the clarnping bars 25 by flanges 28 V These members are positioned on the bars 25 before he cloth 23 is stitched thereto. The flange 29 on one side of each of the locking plates 27 is formed only in the central portion, thus leaving the outer portions of this edge of the plate free for forming bearings 31 and 32, by curling the edge of the plate 27. A pivot pin 33 is supported in the bearings 31 nd 32 thus formed and at its central portion engages with a similarly formed bearing 34 provided on either edge of a connecting plate 35. Each connecting plate 35 serves as a spacing and connecting means for a pair of comp ementary looking plates 27 and together therewith forms a fastening unit.

An actuating member or shifting bar 36 is secured at various points along its length to the connecting plates 35 of the fastening units (which in the present instance are two innumber). A lug 37 formed at each end of the shifting bar 36 provides a means for grasping the bar to simultaneously shift in either direction the longitudinalpositions of all of the locking plates 23. The position of the bar is so related with the remaining ele ments that movement in one direction permits of the release of the fasteners 27 on one side of the sraclz leaves 13, while move ment in the opposite direction from a vertical position, permits of the release of the fasteners on the opposite side of the leaves.

As shown in F 6, each of the locking plates 27 is provided with. a pair of elongated apertures 41 and 42 adapted to cooperate with the reduced portions 18 and 19 of the posts 16. Each aperture 41 is formed with a slot 43 of a width designed to cooperate with the groove 22 of the reduced portion 18 or 19, and with an enlargement 44 at one end of the slot to permit entrance or removal of the reduced portion from the aperture when the parts are in proper longitudinal relation. The apertures 42 have groove-engaging slots 45 similar to the slots 43 of the apertures 41 but they are provided with en largements 46 at each end of their grooveengaging slots.

From the foregoing, it will be evident that when the locking plates 27 are so adjusted longitudinally, that all of the reduced portions 18 and 19 are disposed midway of the apertures 41 and 42, as shown in Fig. 1, the leaves are locked securely between the trans fer bars 14 and 15. When, however, it becomes necessary to change a sheet or to change the position of a sheet, the alteration may be efiected by pushing the lower lug 37 of the shifting bar 36 inwardly (upwardly as viewed in Fig. 6). This places the apertures in the locking plate 27 shown on the left-hand side of Fig. 6 in such a position that this plate and all-similar locking plates 27 on the same side of the binder may be lifted from engagement with the reduced portions 18 and 19 and dropped into the position shown in Fig. 2. The same operation places the apertures in the right-hand locking plate 27 in position so that, while the reduced portion 18 of the bar 15 is held in locked relation with the aperture 41, the reduced portion 19 of the bar. 14 is in registry with one of the enlarged portions 44 of the aperture 42, thereby permitting the bar 14 and its associated posts 16 to be lifted from the pile of leaves 13. If it is desired to' effect the change of leaves at some point between the top and bottom of the stack, all of the leaves above the point where the change .isto be made may be removed with the bar 14.

By so doing, the removed sheets may be held incorrect alignment by the leaf posts 16 on the bar 14 while the change is being made.

If the leaf to which access is desired happens to be closer tothe bot-tom of the stack, or if the book happens to be lying so that simple, practical. means for readily changing.

the leaves in binders of this type has beenprovided, and while a detailed embodiment has been described, it is understood that numerous changes in size, shape and arrangement of parts may be made without departing from the spirit and scope of the invention as defined in the appended claims. 1
